iOS App Store (2008)

The App Store took a revolutionary product --the iPhone-- and took it to another level, where suddenly the user experience could change near-instantly. Need a piece of software to finish a job, or a game to entertain you for a few minutes? The App store put a world of software at your fingertips. It also created a massive infrastructure for independent developers, allowing them to easily distribute their work and make money from every sale. As of January 2011, more than 10 billion apps had been downloaded from the store.
